Hubble captures rare Uranus eclipse

The Hubble has taken pictures of a never-before-seen astronomical alignment of a moon traversing the face of Uranus, and its accompanying shadow.
Though such “transits” by moons across the disks of their parents are commonplace for some other gas giant planets, such as Jupiter, the satellites of Uranus orbit the planet in such a way that they rarely cast shadows on the planet’s surface.
